Previously the anchors and dependencies that allow external hooks were
all in the main ::heat class. However, if you wanted to include just
::heat::db::mysql, then it would fail, since it assumed the main heat
class was included. This moves all of those resources and relationships
into a new class, ::heat::deps. All of the classes will now include
this class so that the anchors and deps are always evaluated even if
only a portion of the classes are used, and even if ::heat isn't pulled
in.
